If he buys 32 bags, he will get 8 free.  That will get him his required 40.

How did you solve this?

radar · Answer

I am trying to get an equation that would show that lol.
4 = paid for + 1 free one.   4+1=5
40/5 =8 buys  (8x4) =32   Gets 8 free one makes 32+8=40

I solved it by looking at the progression you started when you asked the question:
 4, 8, 12, 16, 20, 24, 28, 32   bought
 1, 2,   3,   4,   5,  6,    7,  8    given
  5  10 15 20  25  30  35  40  Total
